To all whom it 17mg concern:

Be it known that I, ALLAN E. Arena, a citizen of the United States, and a resident of Lorain, in the county of Lorainand State of Ohio, have invented certain new and useful Improvements in Variocouplers, of which the following is a specification.

This invention relates to improvements in variocouplers.

The present invention more particularly relates to mounting means for vario-cou- Other objects will hereinafter appear in I the detail description to follow.

The invention is illustrated by way of example in the accompanying drawing,'in; which:

Figure 1 is a. view in side elevation of a variocoupler mounted'upon a panel in accordance with the present invention and ,with parts broken away to morev clearly illustrate the same.

Figure '2 is a perspective view of the mounting-means for the rotor and station ary coils.

Referring to the drawings more particularly P indicates a panel, and C a casting upon-which there is mounted the rotor R and stator or stationary coil S. A

More particularly the casting C comprises a cylindrical body portion 10 which terminates at its one end in enlargement 11 with which there isformed a base flange 12. The enlargement 11 is formed with an arm 13'which extends downwardly and less than 90 to the body portion 10. The arm 13 is preferably of the length and shape provided with a plurality of screw receiving openings 14. The base -flange 12 is also provided with a plurality of screw receiving openings adjacent its free edge and preferably the inner face of this flange is machined. Thebody member 10 has extending its entire length a bore 16 and also this member provided adjacent its end with 2 transverse groove 1?.

The stationary coil S may consist in a cylindrical shell 18 upon which the wind ing 19 of suitable wire is placed. The rotor It may also consist of a cylindrical shell 20 and winding 21 and, of the diameter shown. It is to be understood however that theiconstruction of the stationary coil andthe rotor need not be as shown as other forms may be used.

The stationary coil S may be secured to the arm 13 of casting C by screws 20 or .the like. The rotor is supported within the stationary winding and normally it may assume the position shown in Figure l. The

rotor *is supported through a bar 21 and.

shaft 22. The bar 21- has' each of its ends I formed with an offset portion 22" which extend in oppositedirections and each portion 22 terminates in a. portion 23 extending at The portion 23 may.

right angles thereto. be secured to the rotor R by. the means of bolts or the like as at 24:.

Apin 25 extends from the shaft 22 at a pointadjacent its forward end andsaid pin has its free end disposed in the groove 17. The forward end of the shaft 22 is threaded. and extended through an opening in the bar 21 said opening occurring at a central point of the bar. The shaft carries a pair of lock nuts 26 whereby to hold the bar 21, a coil spring 25 is interposed between the forward end of member 10 and the innermost look not .26. through the member N and also through the panel P. A dial D having the usual knob -K may be secured to the outer end of shaft The shaft 22 extends entirely 22. The casting is secured to panel P by machine screws or the like as at 27. I

By turning the shaft 22 through the knob K the rotor R can be rotated from its full line position shown in Figure 1 to the dotted line position shown in the same view. The pin 25 limits the rotation of the rotor.- The pin 25 also cooperates with the spring 25 for holding the rotor R in its adjusted position.

Vlnle the present invention is shown to mount a vane-coupler 1t is obvious that it may be employed for mounting similar radio v frequency transformers and therefore it should be understood that the invention is not to be limited illustrated and described tnrnable within the tubular member, a coil supported by the arm, and a second coil supported by the shaft and within the first named coil.

2. In a device of the character described,

a casting or bracket comprising a tubular portion terminating at one end in a laterally extending base llange and formed at the last-nanied end of the tubular portion with a. forwardly extending arm. said arm being 16 disposed at an angle to the/tabular portion,

a shaft journaled by the tubular portion. and a pin extended from said shaft and disposed in a transverse groove or slot in' said tubular portion. whereby to limit the 20 turning movement of jhc shaftin either direction andalso hold said shaft against longitudinal movement.

3. In a device of the character described, a casting or bracket comprising a tubular portion/terminating at one end in a base flange extending laterally therefrom,an arm extending forwardly with relation to the base flange and at an angle to the tubular.

portion, a shaftjo'urnaled by the-tubular so portion, a pin extending laterally from the shaft and disposed in a transverse groove or slot in the tubular portion, whereb to limit the thrning movement of the s att and hold the same against:- longitudinal movement, and means whereby to yieldably press the shaft in one direction.

4. In a device of the character described a casting or bracket comprising a tubular portion terminating at one end in a base- 40 flange extending laterally therefrom, an arm extending forwardly with relationto the base flange and at an angle to the tubular portion, a shaft journaled by the tubular portion. a pin extending laterally from the 46 shaft and disposed in a transverse groove portion at each end of the'cross arm. a rotorsecured to the ollset portions of the cross arinand its longitudinal axis disposed at an angle to the similar axis of the shaft,

anda stator encircling the rotor and having its longitudinal axis extending parallel to the similar" axis ot the rotor.

' 3. A. vario coupler comprising a supportin l "ticket including a tubular portion. a base flangev extending laterally from the one end ol said tubular portion, whereby the bracket may be secured to a support, a shaft rotatably supported by the tubular portion, means for supporting a rotor at one end of the shaft so that its longitudinal axis is disposed at an angle to a like axis of the shaft, and a stator encircling the rotor and having its longitudinal axis parallel to the similar axis of the rotor.

7. A vario coupler comprising a supporting bracket including a tubular portion, a base flange extending laterally from one end of said tubular portion, whereby the bracket nay be secured to a support, a shaft roatahly supported by the tubular portion, means for supporting a rotor at one and at the shaft so that its longitudinal axis is disposed at an angle to a like axis of the slut it. an arm extending from the base flange and disposed at an angle to the longitudinal axis of the shaft, and a stator supported by said arm and disposed with its longitudinal axis parallel to the similar axis of the rotor.
